To all whom it may. concern: y l

Be it known that I, CUsHING C. HARLOW, a citizen of the United States, residing at Brockton, in the county of llymouth and State of Massachusetts, have invented certain new and useful Improvements in Lubricators; and I do hereby declare that the following is a full, clear, and exact desoript-ion'of the invention, which will enable others skilled'in the art to which it appertains to makeand use the same.

My invention relates tolubricators; and it has for its object to provide improved means for regulating the supply of the lubricant, and to so locate the devices for this purpose that thef may be easily and conveniently operate A further object of the invention is to improve the details of construction of th lubricator for which Letters Patent No. 295,919 were granted nie April 1, 1884,'and to pr.0 vide a device of this character which shall combine simplicity of construction with ease and efficiency of operation and durability in use.

With these ends in view, the invention consists in' the improved construction and combinations of parts hereinafter fully described,- and pointed out in the claims.

In the drawings, Figurel is an elevation of a lubricator constructed in.accordance-with my invention. Fig. 2 is a plan view of the same with the cap or cover removed. Fig. 3 is a vertical section on the line x Fig. 2. Fig. 4 is a vertical section on the line y y, Fig. 2. Figs. 5 and (i are detail views, as w'ill be more fully mentioned.

In the accompanying drawings, in which like letters of reference indicate corresponding parts in all the iigures, A represents a suitable base, which is provided with au intcriorly-tlueaded flange, a, .which is adapted to rcceive`the exteriorly-threaded end of thei side rt', which is cylindrical inform and prei'- crablyof metal.-

Extending downwardly from the under side Aof the base A a neck, a, which is cxteriorly threaded to engage a threaded opendesired point for the attachment of ing at the the lubricator. Said neck is also preferably 5o provided with a 4flanged portion, vai, having angular sides for the reception of a wrench,

by which means it may be firmly tightened to position.

4 lVithin the base A are provided upwardly- 55 projecting posts a, which extend from the bottom or door of said base.

B represents rods having threaded ends, which ends are seated and held in place in the openings of the upwardlyprojccting posts, 6o said 'rods extendinga short distance above the upper end of the side c. The said rods B, in conjunction with the side a', serve to support a top' piece, a5, which is provided on itsinner side, near the,lower end thereof,'with a cir- 6 5 cumferential shoulder, a, which shoulder rests and is supported upon the upper edge of the side a. Said top piece is of a less circumference at its upper end than for its remainder or body portion, thus forming a circunifercntial seat or shoulder, al, the purpose of which will appear more fully hereinafter.

Extending inwardly from opposite points on the interior of the top piece, a5, are bearing-castings b, which are provided with holes 7 5 or openings for the passage of the upper ends of the rods B. The upper ends of said rods B are threaded, as shown, and fitting upon these ends are nuts b', which are located,when ltightened uppp the threaded ends of the said 8o rods B, lin seats b" It will thus be seen that when said nuts are tightened the cap-piece will be prevented from turning, and willl also be held against displacement or accidental detachment from the side a. The top piece, S5 a5, and the bearingcastings are provided with registeringopenings,which serve as a bearing for a rock-shaft, b, which extends across the reservoir. One end of said rock-shaft extends outside of and beyond the top piecewher e it 9o has attached to it 'in any convenient or suitable manner a rocker-arm, b5, which is adapted to be connected with any suitable moving part of the engine, by which means the said arm and'shaft areoscillated to aetuate the oil-forc- 9 5 ing devices of the lubricator.

`Upon the rock-shaft b, between the two bearing-castings, is mounted a pinion, If', which i for the passage of pins,which pins pass through openings iu the rock-shaft, and thus hold said pinion rigidly upon the rock-shaft.

Upon the Vinner side of the base, and pref- .erably cast integral therewith, is a box or chamber, C, having threaded openings c c c2, located, respectively, upon the upper side of said box or chamber at the inner end wall thereof, and one (the opening c2) in the side of the base, so as to communicate with the interior of said box, all of said openings being threaded.

Fitting in the ppening on the upper side or top of said box is a tube, c, threaded at its lower end..' The upper end of said tube is re duced, and clamped upon said reduced upper end is a guide, c", consisting of the sides c,

connected by the baek,wall or plate, thus,

leaving said guide open on its front side.

D represents a rack which has a sliding' movement in the guide c5, and attached to said rack or formed integral therewith is a rod or 'pision`,E, which is located in the tube t?. and is worked therein when the rock-shaft is oscillated to operate the rack D.

I have mentioned that the top piece was of a less circumference at its upper end than for its remainder or body portion; and itting upon said upper end, and resting upon the seat or sheulderbefore mentioned, is a removable cap or covergci, which incloses and protects the working parts, and'preventin'g the ingress of' dust or other'fextraneous matter to the contents of the reservoir.

F represents aE tube which is exteriorly threaded at its i nnerjeud, .this end being adapted to engagenthe threaded 'opening c of the box or casing and thelhase A. s'

Within the tube Eis formed a valve-seat, d, which ,conical in for1n,` and adapted to t the sai seat is a valve,- d. The said valve d is pointed or conical in shape to iit its seat d in the tube F, and is also contracted orsrnaller in diameter at said conical end than the dian1- eter or bore in the main portion of the tube F, so as to'form apassage around it and within the tube for the lubricant when the valve is unseated. The said contracted portion is provided with an opening or series of openings for theV passage of the fluid through it.- The stem or body portion of the valve is tubular andfits in the tube F, which forms aguide for it in its movements from and to its seat, and a spiral "same with its ends, is a gauze or net cylinder,

e', which acts as a strainer and prevents foreign sedimentary or gritty mat-ter from entering the valve in said tube, which I will now proceed to describe. The tube G is provided with a valveseat, e2, valve e3, and spring e, similarly constructedand arranged to the one already described-located inthe tube. The lubricant, however, passes through anopening or openings in the tube G, being rst strained by the gauze cylinder. A collar, f, is lit-ted upon the outer end of the tube G, and fitted upon said collar f is asnpplemeutal collar, f. To control the flow of the lubricant through the tube G, Iemploya valve, f, which consists of a rod or stem, f3, adapted to tit the tube G. This rod or stem fa is provided at asuitable point upon its length with a threaded portion, f, which is adapted to portion of said opening or openings, whereby the quantity of .lubricant allowed to. pass through said openings in a given time is decreased.

Upontheouter end of the stem f3 is provided a disk, g, having a milled edge, in order that it may be more easily moved. The face IOS of said disk is provided witha series of figures or characters, `as shown, which serve as a guide or index for operating the stem to control the dow of the lubricant.

The working parts of the lubricator before described are, with the exception of the rockerarm, located within the reservoir, or so connected therewith-as to be thoroughly'lubricated.

The rocker-arm, as before described in my patent before referred to, is capable of being operatedv in any position by either a vertically or horizontally moving part of the engine.

Simplicity of, construction' and eiective- A ness of operation have been the chief' points sought to be gained in constructing this device, and it will be seen from the above description, taken in connection with th'e accompanying drawings, that such are the adl vantageous features of my invention.
